  1. Patterns for Cloud Computing Solution Architect Briefing zoli.herczeg.ro Taken from Simon Guests’ work at TechEd Berlin 2009

  2. This is Jim Patterns for Cloud Computing

  3. Jim’s Boss (the CIO) has asked him to “move their company to the cloud!” Patterns for Cloud Computing

  4. He’s seen many great things on cloud computing/Windows Azure Patterns for Cloud Computing

  5. …but he’s still a little confused Patterns for Cloud Computing

  6. He still doesn’t quite understand what types of applications make sense in the cloud Patterns for Cloud Computing

  7. He also wonders how other organizations are using the cloud Patterns for Cloud Computing

  8. What patterns have other people learned – and can Jim re-use for his applications? Patterns for Cloud Computing

  9. Validate what you may have heard and seen so far Provide you with 5 patterns for cloud-based applications Show you how to implement these patterns using Windows Azure

  10. Application runs on-premises Application runs at a hoster Application runs using cloud platform Buy “Software as a Service” A hosted application that I buy from a vendor “Packaged” Application An application that I buy “off the shelf” and run myself Hosted “Packaged” An application that I buy “off the shelf” and then run at a hoster Build vs. Buy Hosted “Home Built” An application that I develop myself, but run at a hoster “Home Built” Application An application that I develop and run myself Cloud Platform An application that I develop myself, that I run in the cloud Build

  15. #1 - Using the Cloud for Scale Patterns for Cloud Computing

  16. “Isn’t the cloud good for applications that need to scale dynamically?” Patterns for Cloud Computing

  17. For example, tax applications Patterns for Cloud Computing

  18. “How does this work?” Patterns for Cloud Computing

  19. Let’s do some white boarding for Jim… Patterns for Cloud Computing

  20. …and when I say white boarding, I really mean it
